SPGs are best used as support vehicles helping the team progress by removing heavily armored targets, such as MBTs, from the battle. Teamwork is needed for those both working with and playing an SPG. Teammates should be asked to call out targets if they are in trouble, and front-line vehicles should be supported in the battle. SPGs are locked to PvE mode. It should be noted that most PvE maps are not suited to allow effective SPG usage due to various obstacles and geography.
